CLOCK-MOVEMENT FRAME.

SPECIFICATION forming part of Letters Patent No. 317,898, dated May 12, 1885. Application filed January 5, 1885. (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIE O. WALTER, a citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Clock-Movement Frames; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art IO to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of referen ce marked thereon, which form a part of this specification.

Figure 1 of the drawings is a front View. Fig. 2 is a side View. Figs. 3 and 4 are details.

This invention has relation to sectional frames for clock-movements; and it consists in the construction and novel arrangement of devices, as hereinafter set forth, and pointed out in the appended claim.

The object of this invention is to provide an improved sectional clock-movement frame whereby it is designed to facilitate the removal of the main wheel and mainspring, and at the same time to preserve the strength of the frame at the arbor-bearing.

In the accompanying drawings, the letter A designates the main portion of the frame of a clock-movement, and B the arbor of the main wheel.

O is the removable section or leg portion of the frame, through which the pivot of the arbor 13 passes, a bearing, D, being made therefor nearthe end of the plate 0.

E is the post to which the end of the mainspring is attached. The outer end of this post is shouldered to engage and support the other end of the plate 0, and through a perforation in the end of the post is passed the key F, which is usually a small piece of wire.

Under the bearing D of the section 0 the Ina-in frame is provided with a notch or slot,

G, having an outward opening or way, II. 5 Vhen the section O is taken off, the end of the arbor of the main wheel is readily slipped out of this notch, and this wheel, with the mainspring, can be easily removed. The notch G is circular, and it receives the inner circular go portion of the wall of the bearing D, which projects therein. K is an offset to this projecting portion of the wall of the bearing, which is formed on the inside of the outer portion of the plate O, and is designed to enter and fully engage the way II of the notch G. The engaging walls of said way, as well as the oftset or block K, are preferably made a little inclined inward toward each other, so that the block will fit closely in the way or passage 11. 6c This block projects inside of the plate z of the main portion of the frame, and isprovided in this projecting part with a perforation, m, for the reception of a key,V, which is usually made of wire. Vhen the frame-sections are con- 6: nected, they are fastened securely in position by the keys V and F. The block or offset K fills the outward opening or way H ofthe notch in the main plate, and, with the key V, supports the plate fully at this weak point, so that the strength of the frame is maintained.

Having described this invention, what I claim, and desire to secure by Letters Patent,

The combination, with the notched main sectionof a clockframe and the mainspringpost, of the removable leg-section having the bearing and its perforated offset filling the notch, the perforations for the post, and the keys passing through the offset and the end of the post, substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.
